In the title. I'd assumed this was a given but after listening to some podcasts I'm not so sure.
Of course you'll be footing it in the towns and mission areas but what about the in between
points where you drive? Can you be driving along and see something neat and hop out
to inspect it? Or for that matter if you don't want to drive can you foot it to your next
destination?

Yes

LOL, it would be absolutely horrible if you couldn't. I'm not sure I could go on playing it after you would get that crappy absolute-linearity feeling, like in that extremely primitive Call of Duty 4 campaign where you couldn't open a single door, had invisible walls everywhere and infinite spawn of enemies unless you cross an invisible line...

Ahh, thank you for that. Funny thing is I've probably seen it before and forgot it. One other question that
I haven't seen asked yet : Do you have the choice to holster your weapon at any point? Reason I'm asking is
because it gets annoying having the gun waving around in your face when your trying to examine/explore.
